To all whom it may conservi Be it known that l, Geenen Wrr'rr,`a citizen of the' United States of America, residing at Scranton, in the county of Lachawanna and State of lfennsylVania, have invented new and uset'ul .improvements in Signaling Systems, of which the following is a. specification. it

This invention relates to improvements in signaling systems .and has particular application to wireless systems wherein the transmission of the signals is accomplished by electromagnetic waves.

In carrying out the present invention, it is my purpose to provide a wireless signaling system which will be found especially useful for transmitting signals between railroadY trains, trains and signal towers and between ships at sea.

It is also my purpose to provide a ortable Wireless signaling ap aratus or out it which may be readily positioned upon the vehicle to which it is applied and which will ernbody, among other features, wave transmitting and receiving sets each including an antenna or aerial, a second antenna or aerial composed of a reflector, and means whereby either of the antennae or aerials may be placed in circuit with the respective set.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereafter set forth in and falling within the scope of the claims.

In the accompanying drawings;

Figure 1 is a view in front"`elevation of an electromagnetic ware signal apparatus constructed'in accordance with/my present invention. Fig. 2 'is a top plan view thereof. Fig. 3 is a diagrammatic View of the apparatus. Fig. 4 is, a Vertical sectional view throu h one of the reflectors. Fig. 5 is an enlarge fragmentary 'elevation of one of the reflectors. Fig. (S is a detail view of a ground plate.` Fig. 7 is a view in elevation, partly in section, of the throttle controlling device. Fig. 8 is a similar view of the device for controlling theI engineers brake valve, and Fig. 9 is a diagrammatic View of the train stopping apparatus.

Referring now to the accompanying drawings in detail the numeral 1 indicates a suitable box-li e structure havin a hinged closure 2 whereby access may e had to the interior thereof, while the numeral 3 designates a standard uprising from the upper surface oi the box-like structure and having pivotally mounted on the upper' end thereof an appropriate form of telescope 4 by means of which the engineer of a train or the signalman in a signal tower, as the case may be, may ascertain the condition of the track ahead or the general conditions of the roadway. At one corner of the box-like structure is a vertical supporting rod 5 having pivotally connected thereto one end of a set of lazy tongs 6 the free end of the lazy tongs carrying a base 7 upon which is swiveled for universal movement an ap ropriate form of Search light 8 connecte in circuit with a battery or other suitable source of electrical energy 9 disposed within the box 1, a switch 10 being located in the circuit so that the search light may be`cut in and out of service. A supporting lu 11 is suitably connected to one sid wall o the box so as to support the free end of the lazy tongs structure when the search light is inactive. By means of the telescope and the search light, the operator using the apparatus may view the way ahead by day and by night.

Each signaling apparatus embodies electro-magnetic wave transmitting and receiving sets, as illustrated diagrammatically in Fig. 3.
